Ear earplugs to wear after the earplugs and ear canal to form a closed space, resulting in external sound through the ear plug shell into the ear canal, that is, we often say that the stethoscope effect.

The stethoscope effect will seriously affect the normal listening.

In order to avoid the stethoscope effect, so the ear earbuds require the wire to try to soften, to avoid friction with clothing. Part of the ear plugs are not soft enough, such as E2C, E5C, etc., but these earplugs stethoscope effect is not serious, which is another way to avoid the. Around the ear! The wire around the ear a week, so even if the wire jitter, it will not produce stethoscope effect.

Third, the main use of different

Ear ear plugs because of close to the ear canal, it can effectively block the external noise, and open earplugs can not play such a role. So in the surrounding environment more noisy place to listen to music or other things, buy ear ear plug is a good choice. As for some people think that ear ear hearing injury, we will talk about in another article. Here is not elaborate. But can be clear that the ear plug in fact not hurt hearing. But to remind you, because the ear plugs sound insulation ability, so on the road is not recommended to wear, after all, safety first.

Fourth, the sound style is different

Ear ear plug because of its closed design, earplugs directly into the ear canal, so the sound is more delicate, the air attenuation problem is relatively small, and open earplugs because the sound through the air attenuation is relatively large, resulting in the details of the natural and delicate. And the ear ear is not enough place to control the low frequency, in a closed structure, so when the low frequency is slightly enough, the reverberation problem will be more prominent, the other dynamic structure itself there is a low frequency of relatively large Features, so in such circumstances.

Fourth, the two on the hearing damage

All along, many people mention ear ear ear, always think of its injury hearing. In fact, this view is caught in a misunderstanding.

Damage to hearing a lot of reasons, such as listening time, volume and so on. Here is mainly related to the volume problem.

We usually hear the sound size is generally between 40-60 dB, so listening, the volume should also be controlled here. The sound of the open earplugs is easily disturbed by external noise, and the human hearing will reflect the decline in power because of noise, so in a noisy environment, will not consciously open the sound to very large. And so back to the quiet environment, and then listen to the same time, will understand the problem. Ear earplugs because of their way of wearing, you can isolate most of the noise, so in noisy environment, generally do not have to adjust the volume, so that the hearing will play a protective role.

But also because of this problem, it is recommended that you walk through the road or when driving must not wear. Otherwise prone to traffic accidents.

Five, ear ear plugs the choice of plastic sleeve

We often ask, what plastic sleeve is better, in fact, there is no uniform answer.

The size of the human ear is not the same, even the same person, the size of the left and right ear canal is often not the same. Select the standard is to see the seal, if the seal is not good, will produce a leak, the sound will be dry, burr, low frequency and other issues. Now ear ear plugs are generally shipped with a number of specifications of the plastic sets, so that we can choose according to their own conditions. Other people say only their own situation, the reference is just to listen to the sense can be compared to determine whether the quality should be achieved, the rest of the role is not big.

Six, ear ear plugs in the sea sets

Ear earbuds of the sea sets and ordinary sea sets of the difference is relatively large, and plastic sets are also many differences. Therefore, alone, the ear sponge sleeve for the cylindrical type, there is a hose inside. Wear sponge pinch small, stuffed into the ears, and then the sponge will own expansion, and the ear canal close. Sponge sets of the advantages of wearing more comfortable, relatively low stethoscope, low-frequency upgrade is relatively large, high-frequency weakened, the disadvantage is easy to be contaminated. So it is recommended sponge sets should often change, the other not to use.
